JOHN G. HAUS, OF WEIRTON, WEST VIRGINIA.

GAS WATER HEATER.

Application filed February 21, 1922. Serial No. 538,358.

To allwkomitmay concern: 9

Be it known that I, JoHN G. HAUS, a

citizen of the United States, residing at h Weirton, in the county of Hancock and State of West Virginia, have invented certain new and useful Improvements in Gas Water Heaters, of which the following is a specification.

This invention relates to improvements in water heaters and has for its object to provide a simply constructed gas heater for hot water boilers.

Another object of the invention is to provide a gas heater for hot water boilers of very simple, inexpensive, yet very efiective construction.

With the above and other objects in View I have invented the device illustrated in the accompanying drawings in which Figure 1 is a side elevational view of a hot water heating apparatus;

Figure 2 is an enlarged vertical sectional view of a hot water heater used in connection therewith;

Figure 3 is a section on line 3--8 of Figure 1; and

Figure 4 is a section on line 4& of Figure 1.

Like reference characters indicated like parts throughout the following specification and in the several views in the drawings-in which, 1 indicates a hot water boiler having a circulating pipe 2 the upper end 3 of which enters the upper wall 4 of the boiler 1, and the lower end 5 of which enters the bottom wall 6 of said boiler. Mounted upon the vertical portion 2 of the pipe 2 is my improved gas hot water heater 7 which consists of a cylinder 8 having a water compartment 9 in its upper end, into the threaded nipple 10v of which the lower end of the pipe 2* is threaded. The bottom wall 11 of said chamber 9 is provided with a threaded nipple 12 into which the upper end of the pipe 2* is threaded. The vent pipe 13 extends vertically through the chamber 9 and opens into the lower portion or heating chamber 14 of said member 8, said chamber being open at its lower end Surrounding the upper portion of the PIP? 2 16within saild chamber 14 is a as ea er connecte with a as Sn 1 1 e 17 through the fusil 18. 3k plliigli ty 3f vents 19 are provided in just below the wall 11.

From the above description it will be seen that a supply of water is always maintained in the compartment 9 directly above the heater and that the cold water passing from the lower portion of the boiler goes up through the heating chamber 15 and di-. rectly between the flames from the burner 16. Heat from the chamber 14 also passes through the vent pipe 13, thus providing a further means for supplying heat to the water in the chamber 9.

' Having described my invention that which I claim is new and desire to procure by Letters Patent is: V

1. A device of the character described, consisting of a cylindrically formed member having a water compartment in its, upper the cylinder 8 end, and aheating chamber, a boiler and I means whereby the water may have free circulation between said boiler and said chamber, a gas burner in said cylinder be: low said compartment, said means embracing water pipe one portion of which projects through said burner.

2. A device of the character described, consisting of a cylindrically formed member having a water compartment in its upper end, and a heating chamber, a boiler and means whereby the water may have free circulation between said boiler and said chamber, a gas burner in said cylinder below said compartment,.said means embracng a water pipe one portion of which proects through said burner, said water compartment having an air passage extending therethrough and into said heating chamber.

In testimony whereof I aflix my signature in'the presence of two witnesses.
